Saw this a week or so ago on Charlie rose. It was very moving, his first interview after publishing Night. He states that his biggest concern is related to the fact that someone opened up a memorial to German prisoners of the Russians who conquered the concentration camps. It pained him deeply that on the site of the genocide, one could have a memorial to the suffering of Nazi POWs.
He evolves quite a bit in his later years. And, I read somewhere else, that there is a longer version of Night in Hebrew, which Wiesel meant to publish in Israel, which never saw the light of day. An amazing soul, may his memory always be honored in the pantheon of the wise.
